Important Information about Generic Meropenem

Generic meropenem contains the same active ingredient as brand-name Merrem. It must meet the same effectiveness and quality standards. This means it is designed to work like Merrem. Studies have shown that generic meropenem is bioequivalent to brand-name Merrem, meaning it has similar absorption and achieves comparable blood concentrations. However, individual responses to medication can vary due to factors such as metabolism, genetics, and other health conditions.

Dosage:

Merrem (meropenem) is an injectable antibiotic available in the following strengths:
• Powder for reconstitution: 500 mg/vial and 1000 mg/vial

Your doctor will determine the dosage and frequency based on the type and severity of the infection, as well as the patient's age and kidney function. It is typically administered every 8 hours via intravenous (I.V.) infusion.

Usage:

Merrem is a potent, broad-spectrum antibiotic reserved for serious or complicated bacterial infections. It is primarily used to treat complicated intra-abdominal infections, severe skin and soft tissue infections, and bacterial meningitis in both adults and children. Additionally, it is a critical treatment for complicated urinary tract infections and healthcare-associated pneumonia. Because it belongs to the carbapenem class, it is often used when other antibiotics have failed or when "superbugs" (multidrug-resistant bacteria) are suspected. It is effective only against bacterial infections and does not affect viral illnesses such as the flu or the common cold.

Mechanism of Action
Meropenem works by disrupting the synthesis of the bacterial cell wall, which is essential for bacterial survival. It penetrates the bacterial cell and binds to specific penicillin-binding proteins (PBPs). These proteins are responsible for building the peptidoglycan layer. That is, the structural "skeleton" of the cell wall. By blocking these proteins, meropenem prevents bacteria from completing their cell wall synthesis, leading to cell wall collapse and eventual rupture (lysis). Meropenem is particularly effective because it is highly resistant to many of the enzymes (beta-lactamases) that bacteria produce to destroy other antibiotics like penicillins and cephalosporins. This allows it to remain powerful even against highly resistant bacterial strains.

A doctor or nurse administers Merrem in a clinical or hospital setting. If you are receiving this medication as part of home-infusion therapy, follow all instructions provided in the product monograph.

The information below summarizes some, but not all, potential side effects, risks, and interactions. Before starting Merrem, it is essential to discuss all possible side effects, risks, and interactions with your doctor or pharmacist.

Side Effects:

The information below outlines potential side effects of Merrem (meropenem). It is not an exhaustive list, and individual reactions can vary.

Common side effects: These are common side effects of Merrem; other side effects are possible. Contact your doctor promptly if any side effects are persistent, worsening, or concerning, or if you experience any other concerning symptoms.
• Diarrhea
• Headache
• Inflammation or pain at the injection site
• Nausea or vomiting
• Skin rash or itching

Serious Side Effects: Seek immediate medical attention or call emergency services if you experience any of the following symptoms:
• Anaphylaxis: Severe allergic reaction involving hives, swelling of the face or throat, and difficulty breathing.
• C. diff-associated Diarrhea: Severe, watery, or bloody diarrhea with stomach cramps and fever.
• Seizures: Especially in patients with existing central nervous system disorders or kidney issues.
• Severe Skin Reactions: Blistering or peeling skin (e.g., Stevens-Johnson Syndrome).

Contraindications:

The following is not an exhaustive list of contraindications. Before starting Merrem, it is crucial to discuss all your medical conditions, past and present, and all medications you are taking with your doctor or pharmacist.

Do not receive Merrem/meropenem if:
• Allergies: You have a known hypersensitivity to meropenem or other carbapenems.
• Severe Penicillin or Cephalosporin Allergy: Use with extreme caution if you have had an anaphylactic reaction to penicillins, as cross-reactivity can occur.

Tell your doctor about all of your medical conditions, past and present, before starting Merrem. This is crucial as certain conditions affect the drug's safety.
• Central Nervous System Disorders: Tell your doctor if you have a history of seizures or brain lesions, as the risk of seizures may increase.
• Kidney Disease: The dosage must be adjusted based on your kidney function to avoid toxic buildup.

Drug Interactions:

Before taking Merrem, discuss all potential risks and interactions with your doctor or pharmacist. For complete and up-to-date information, please visit the highlights of prescribing information at https://labeling.pfizer.com/ShowLabeling.aspx?id=9318.

Provide your doctor with a complete list of all your medications, including prescriptions, over-the-counter (OTC) drugs, vitamins, herbal supplements, recreational drugs, and any significant dietary changes, as these may interact with Merrem. Meropenem may interact with other medicines, including but not limited to:
• Oral Anticoagulants: Like many antibiotics, meropenem may increase the blood-thinning effects of warfarin.
• Probenecid: This can slow the elimination of meropenem from your body, leading to higher meropenem levels in your bloodstream.
• Valproic Acid/Sodium Valproate: Meropenem can significantly lower the levels of this seizure medication in your blood, increasing the risk of breakthrough seizures.

Pregnancy and Breastfeeding:

Merrem should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Small amounts of meropenem pass into human milk. Monitor your nursing infant for diarrhea or thrush. Inform your doctor if you are breastfeeding, planning to become pregnant, or breastfeeding.

Use in Children:

Merrem is approved for use in pediatric patients (aged 3 months and older). For children, the medical team carefully calculates the dose based on the child's weight and the specific infection being treated.
